A LONG-SHORT, single-instrument, pure-price STRUCTURAL BREAKOUT position strategy on BTCUSDT.BINANCE (USD-M perpetual), daily bars, holding weeks-to-months. This is a deliberate family change away from the momentum-CONFLUENCE templates that this session has exhaustively falsified (BTC/ETH/SOL/AVAX/ADA/BNB, 4H/1H/12H/daily, macro-gate, triple-TF — all dead) and away from my other pivots (calendar net-losing, session negative-gross-edge, macro TSMOM CI-straddling-zero). The mechanism is a STRUCTURAL channel breakout: enter LONG only when BTC prints a new ~6-MONTH HIGH, SHORT only on a new ~6-month LOW — a rare, regime-DEFINING event (BTC entering price discovery / a confirmed new bull or bear regime), NOT a rolling short-window channel. This is explicitly DISTINCT from the abandoned 20-day-1D 'BTC Donchian' (which died as an outlier-mirage — one 2021 day = 82% of its return): (1) a 6-month structural extreme fires only ~3–6x/yr on genuine regime shifts, not on daily noise; (2) VOL-SCALED sizing downsizes into high-vol spikes so no single day can dominate the return distribution (the specific fix for the outlier-mirage / deflated-Sharpe failure); (3) it is a position trade riding the discovery leg, not a fast channel scalp. This is the archetype professional trend-following CTAs actually run (breakout-and-hold on structural levels), which survives precisely because it captures the rare large regime legs where BTC's autocorrelation is strongest. NOT a mean-reversion fade (L53), NOT a volatility-compression squeeze (L54 — this is a structural directional break with documented price-discovery continuation, not a low-vol pop), NOT a cross-sectional basket (L52), NOT a NON-PRICE-feed gate (L46), NOT options/COIN-M (L50/L51), NOT calendar/session. Only 2 parameters (channel length, chandelier multiple) → low deflated-Sharpe hurdle. On BTC (only asset with demonstrated tradeable structure). Risk profile: vol-scaled notional so daily position vol ≈ a fixed budget, ~2% equity risk anchored to the chandelier; capped at 25% of equity*leverage; 2x leverage cap (reads self.config.leverage).
